Similarly, the structural cam 450 and theadjustment cam 452 are operable between a blocked position and a removedposition. The blocked position of the structural cam 450 and theadjustment cam 452 corresponds to the locked position of the lockinghook 338. Similarly, the removed position of the structural cam 450 andthe adjustment cam 452 corresponds to the unlocked position of thelocking hook 338.

Referring now to FIG. 11A, the locking hook 338 is shown in the lockedposition. In the illustrated embodiment, the side edge 596 of the firstflange 580 of the locking hook 338 is substantially flush with the topedge 508 of the adjustment cam 452. The tab 494 of the adjustment cam452 is not fully engaged with the notch 524 of the structural cam 450,and the return spring 624 is in a neutral position. When the lockinghook 338 is in the locked position, the second flange 588 is positionedto prevent the striker pin 12 from being removed from the opening 334.To secure the striker pin 12, the end 606 of the locking hook 338 isaligned with the downward extending flange 416 of the sector arm 16. Thetop edge 508 of the adjustment cam 452 abutting the side edge 596 of thefirst flange 580 of the locking hook 338 prevents the locking hook 338from rotating out of the locked position. The locking hook 338 willremain in the locked position until acted upon by a force that alsorotates the adjustment cam 452 and the structural cam 450 out of theblocked position.

Referring now to FIG. 11B, when the latch assembly 168 is actuated bythe first or second latch cable 130, 132, a force F1 is applied to thestructural cam 450 by the first or second latch cable 130, 132. Theforce F1 applies tension on the return spring 624, resulting in a forceF2 being exerted on the locking hook 338 through the return spring 624.The side edge 596 of the first flange 580 of the locking hook 338remains in contact with the adjustment cam 452. When the force F1 isapplied to the structural cam 450, the structural cam 450 rotates aboutthe third connection pin 394 until the tab 494 fully engages with thenotch 524 of the adjustment cam 452. When the tab 494 fully engages withthe notch 524, a moment M1 is applied to the adjustment cam 452 andcinching spring 440 (not shown). The moment M1 is applied generallyclockwise about the third connection pin 394 as the tab 494 remainsfully engaged with the notch 524 and the foot 516 of the adjustment cam452 begins to move in a clockwise direction.

Referring now to FIGS. 11C and 11D, the first or second latch cable 130,132 continues to apply the force F1 to the structural cam 450. Thestructural cam 450 continues to move in a generally rearward direction,applying the moment M1 to the adjustment cam 452. As the adjustment cam452 rotates, the top edge 508 of the adjustment cam 452 is graduallymoved out of contact with the side edge 596 of the locking hook 338.When the top edge 508 of the adjustment cam 452 is removed from contactwith the side edge 596, the locking hook 338 is free to rotate about thesecond connection pin 392. The structural cam 450 continues applyingtension to the return spring 624, continuing to apply the force F2 onthe locking hook 338. As the force F2 on the locking hook 338 increases,a moment M2 is applied generally clockwise about the second connectionpin 392, rotating the locking hook 338 into the unlocked position, asshown in FIG. 11D. The locking hook 338 will remain in the unlockedposition until it receives the striker pin 12. When the striker pin 12is received by the opening 334 defined by the locking hook 338, thestriker pin 12 pushes the first flange 580 upwards when it contacts theside edge 596 of the first flange 580. When the locking hook 338 reachesthe locked position, the cinching spring 440 rotates the adjustment cam452 back into the blocked position, allowing the side edge 596 tocontact the top edge 508 of the adjustment cam 452 and securing thelocking back into the locked position.

As discussed elsewhere herein, the second arm 804 of thesector arm 16 includes the gear edge 838. The gear edge 838 includes aplurality of gear teeth 930. A pinion 934 is disposed proximate to thegear edge 838. The pinion 934 is generally cylindrical and may include aplurality of gear slots 938 defined by a lateral edge 942 of the pinion934. The plurality of gear teeth 930 is configured to be received by theplurality of gear slots 938. The plurality of gear teeth 930 and theplurality of gear slots 938 allow the second arm 804 to be selectivelyoperable between the design position, the raised position, and amultitude of positions between the design position and the raisedposition. As shown in FIGS. 12B, 13, 14B, 15, 18A, and 18B, the pinion934 is actuated using an actuator 960 and a cable 964 operably coupledto the base frame 74. When the actuator 960 is engaged, it ratchets thegear edge 838 upward to allow the second arm 804 to raise the base frame74. As the second arm 804 raises, the hinge arm 188 gradually rotates aswell to allow the base frame 74 to remain substantially parallel to thetrack assembly 14 as it raises. The second arm 804 is operable when thefirst arm 800 is in any position. By utilizing the raised position, itis possible to increase the cone of entry C shown in FIG. 14B to allowaccess to space rearward of the seating assembly 10. It will beunderstood that the number of gear teeth 930 illustrated in the presentdisclosure is exemplary only, and the number may be increased ordecreased without departing from the scope of the present disclosure. Itis also contemplated that the second arm 804 may be of any shape or sizewithout departing from the scope of the present disclosure.
